Nestled between lush mountains and the Mediterranean coast, Lake Köyceğiz is one of Türkiye’s largest and most breathtaking coastal lakes. Covering an impressive area of 5200 hectares, this alluvial set lake is a haven for nature lovers, photographers, and adventure seekers alike.

Fed by the Namnam and Yuvarlakçay rivers, as well as countless mountain brooks, the lake maintains its vitality year-round. What makes it even more unique is its connection to the sea via the Dalyan Channel — a narrow, reed-fringed waterway that winds past the ancient city of Kaunos before meeting the Mediterranean at the famous İztuzu Beach.

The lake’s surroundings form the heart of the Köyceğiz-Dalyan Special Environmental Protection Area, one of Türkiye’s most important ecological reserves. Here, vast marshes, endemic Oriental Gumtrees, dragonflies, colorful bird species, and ancient ruins blend into a mesmerizing natural landscape.

A Paradise for Explorers
Whether you prefer a leisurely boat tour, kayaking, or hiking around the lake, the beauty of Köyceğiz will captivate you. The northern and eastern shores are flat plains ideal for walks, while the southern shores rise into forested hills like Ölemez Mountain (937 meters) and Bozburun Hill (556 meters).

The lake itself hides secrets — including five small islands, the most famous of which is Hapishane Adası (Prison Island). Once used for military purposes and later as a prison, it now stands deserted, surrounded by stories of forbidden love and ancient mysteries.

A Unique Geological and Ecological Treasure
Formed around 7500 years ago during powerful earthquakes, the lake area is also rich in sulfurous hot springs, especially near Sultaniye Spa, known for its therapeutic waters. The combination of fresh water, warm sulfuric water, and mild sea tides creates a fascinating ecosystem where even the sands of İztuzu Beach seem to shimmer with life.

Lake Köyceğiz is not just a body of water — it’s a living, breathing wonder. It’s a perfect destination for birdwatching, nature photography, reptile spotting, or simply relaxing amidst stunning scenery.

Visiting Lake Köyceğiz offers a rare chance to witness a timeless connection between land, water, and ancient stories — a journey into the very soul of Türkiye’s Aegean coast.
